3 Claims.

The present invention relates to ironer rolls for use in rotary ironers. The object of my invention is to provide an improved construction and arrangement for securing the pad on the roll and for a consideration of what I believe to be novel and my invention attention is directed to the accompanying description and the claims appended thereto.

In the accompanying drawing,.Fig. 1 is a seclo tional end elevation of an ironer roll embodying my invention; Fig. 2 is an enlarged sectional view showing the manner of securing the pad to the roll, and Figs. 3, 4, 5 and 6 are figures showing the sequence of operations in securing the pad to l5 the roll.

Referring to the drawing, I have shown my invention in connection with an ironer roll which comprises a sheet metal cylinder I having a pad 2 0n the outer surface thereof held in place by a pad cover 3. The roll is suitably supported for rotation about its axis in a manner not shown and when used in a rotary ironer may cooperate with a heated shoe having an arcuate surface bearing on the outer surface of the roll. The

8l rotation of the roll feeds the material being ironed under the heated shoe. No illustration is made of such a rotary ironer since ironers of this type are well known in the art.

On the outer surface of the roll is a longitudinal lo series of projections I projecting at an acute angle to the surface of the roll in the direction of rotation of the roll. In the assembly of the ironer pad on the roll one end of the pad cover is forced over the projections l, as shown in Figs. 3 and 4,

the free end of the pad cover extending from the projections in the direction of rotation of the roll. Loops 5, which are stitched or otherwise secured to the underside of the pad 2, are hooked over the projections 4 as shown in Fig. 5. 'I'he n free end of the pad cover 3 is then extended up over the end of the pad to the outer surface of the pad and the pad and pad cover are wrapped tightly around the roll in the direction opposite to the direction of rotation of the roll. The besinning of the wrapping step is shown in Fig. 6. As shown in Fig. 1, the ends of the pad form a butt joint so that the outer surface of the pad is smooth. Bince the pad is wrapped around the roll in the direction opposite to the normal direction of rotation of the roll, the friction between the roll and the cooperating ironer shoe tends to wrap the pad more tightly around the roll. Instead of providing loops 5 on the underside of 5 the pad, itis obvious that the projections 4 could be hooked directly into the pad. As shown in Fig. 2, the projections 4 extend through the portion of the pad cover between the abutting ends of the pad into the other end of the pad. This l0 still further tends to anchor the pad to the roll.

What I claim as new and desire to secure by Letters Patent of the United States, is:

1. In an ironer, a roll having projections thereon, a pad hooked over said projections at one end l5 and wrapped around the roll, and a pad cover on said projections beneath the pad and extending between the roll and said end of the pad in a direction opposite that in which the pad is wrapped, up over said end of the pad, and around the pad in the direction in which the pad is wrapped.

2. In an ironer, a roll having projections thereon, a pad, loops on the underside of the pad at one end thereof hooked over said projections, the pad being wrapped around the roll, and a pad cover on said projections beneath said loops and extending between the roll and said loops in a-` direction opposite that in which the pad is wrapped, up over said end of the pad, and around 3 the pad in the direction in which the pad is wrapped.

3. In an ironer, a roll having projections thereon extending therefrom in the direction of rotation of the roll, a pad hooked over said projections at one end and wrapped around the roll in a direction opposite to the direction of rotation of the roll, the ends of said pad forming a butt joint and said projections extending into the other end of the pad, and a pad cover on said projections beneath the pad and extending between the roll and said first end of the pad in a direction opposite that in which the pad is wrapped, up between the abutting ends of the pad, and around the pad in the direction in which the pad is wrapped.
